What does one millibar represent?

One millibar is a unit of pressure equal to 100 pascals and is widely used in meteorology to express atmospheric pressure.

Why use foot water (4°C) as a pressure unit?

Foot water (4°C) expresses pressure as the hydrostatic load from a one-foot column of water at 4°C, useful for hydraulic and fluid pressure measurements.

Can I use this conversion for water at temperatures other than 4°C?

This conversion assumes water at 4°C as a standard reference; using other temperatures may result in less accurate pressure equivalence.

What Is This Tool?

This tool converts pressure measurements from millibar (mbar), a unit widely used in meteorology and atmospheric sciences, to foot water (4°C) (ftAq), a hydrostatic pressure unit based on the pressure exerted by a one-foot column of water at 4°C. It is beneficial for translating atmospheric pressure readings into hydraulic head values.

How to Use This Tool?

Enter the pressure value in millibar (mbar)
Select foot water (4°C) (ftAq) as the target unit
Click convert to see the equivalent pressure in foot water
Use the conversion result for hydraulic or fluid system calculations

Key Features

Converts pressure from millibar to foot water (4°C) units accurately
Uses a standard conversion rate based on water density at 4°C
Browser-based and easy to use without installation
Helpful for applications in meteorology, aviation, hydraulics, and fluid systems
Includes examples to guide conversions

Examples

10 millibar = 0.334562292 foot water (4°C)
100 millibar = 3.34562292 foot water (4°C)

Common Use Cases

Reporting atmospheric pressure in terms useful for hydraulic engineering
Determining pump head based on pressure readings
Converting barometric pressure for HVAC and fluid instrumentation monitoring
Measuring static head in groundwater and well pressure assessments
Calibrating devices that require hydraulic head input in feet of water

Tips & Best Practices

Ensure water temperature references 4°C for accurate conversion
Use this conversion primarily with hydrostatic pressure related to water columns
Validate measurements from barometers or instruments before conversion
Apply converted values properly within hydraulic and fluid dynamics contexts
Be aware of unit relevance depending on your specific use case

Limitations

Conversion assumes water is at 4°C; temperature deviations can affect accuracy
Foot water unit applies only to hydrostatic pressure related to water density
May not be meaningful for pressure measurements outside water or fluid columns
Conversion does not account for other fluid types or variable densities
